It's not guaranteed to be your problem, but it could be your power steering pump.

Just making this thread to help anyone experiencing problems remedy their problem.

A while ago, my car started making a squealing sound on cold startups. I thought it was just something that would go away, so I ignored it. A few months later, the squeal gets a lot louder and my steering feels really slow and heavy. At a stop, I turn the steering wheel and it takes a second for the power steering to kick in.

I go straight home to pop the hood and look for any problems. Half my belt is burned off, there's a loud squeal, and part of my frayed belt was slapping everything it could. I quickly turn the car off to examine it more.

The power steering fluid reservoir was 80% empty and fluid was getting all over the place in my engine bay and underneath. The engine bay was smoking due to the fluid hitting my passenger side header.

I called a flatbed and got it towed down to the nearest Nissan dealership, which was where I was originally headed to get my f'd up lower controls arms replaced. So now I'm late for my appointment, and down there with twice the problems I originally planned for.

Just got a call from the dealer confirming the problems. With emergency shipping (1 day), the total came out to $700, which includes the parts, labor, and a new belt. There goes my "fun" fund...

Just throwing this out there. If you experience a squealing sound from under the hood and you don't know what it is... be wary.

I just bought a 03 350z and it's a fixer upper haha.
anyways on cold starts it squeals so loud my neighbor's probably hate me but it seems to have a new belt and when the squealing stops i put it in reverse and it starts squealing again so I put it in park again it stopped after a second or two but then I move my steering wheel and the squealing starts again could this be my (PS) Pump. And if so does anyone know where to get the right one

" There is a guy on youtube that has a video on it. It's a good idea to do this every year or so to keep them from getting too dry, specially if you live in a desert area like mine where its 120 in the summer.
